Abstract: Double buffering of serial transfers is provided in order to allow for increased serial transfer rate without requiring increased internal processing speeds. A laser driver serial controller serially receives a word including address bits and data bits. During a write operation, the address bits are serially shifted into an address shift register of the laser driver, and the data bits are serially shifted into a data shift register of the laser driver. After the address bits and data bits are completely shifted into the respective address and data shift registers, the address bits and data bits are transferred in parallel to address and data holding registers of the laser driver. After the parallel transfers of the address bits and data bits from the address and data shift registers to the address and data holding registers, the address and data shift registers are available to serially receive additional address bits and data bits of an additional word.

Abstract: Methods and system are provided for automatic power control of a laser diode, e.g., in a laser driver. In accordance with an embodiment of the present invention, a power controller includes a detector circuit adapted to detect the output of the laser diode and to produce a measured output therefrom. A comparator compares a desired output to the measured output, and produces an error signal therefrom. The error signal is provided to an integrator circuit that produces an integrated error signal. At least one digital-to-analog converter (DAC) uses the integrated error signal to produce a current drive signal that drives the laser diode.

Abstract: In one configuration, the present system includes a top rail, a bottom rail, and a side rail that form an open-box automobile frame rail. At least one truss portion forms a diagonal between the top and bottom rails.

Abstract: Organoclays made from smectite-type clays are described as rheological additives for clear systems including clear coat paints, lacquers, varnishes and personal care products. Such additives impart desirable properties to such systems and do not adversely impact the desired properties of clarity and transparency required in such systems.
